User Manual S200 WCS
Update August 2021
A deviation of the measuring value is possible after an automatic probe cleaning
process, since the probe has been newly polarized, which can result in a temporarily
higher measuring value.
If a calibration of pH or redox value is required, this calibration should be carried out
first.
After pH or Redox have been calibrated, wait for at least 15 minutes before calibrating
the chlorine/chlorine dioxide/ozone probe. During this time, the sample water must flow
through the valve again.
This calibration is a one point calibration.

1. After flushing with about 250 ml of water, open the sampling tap on the valve and
take a water sample.
2.
Carry out a comparative measurement.
If the deviation is less than 0.10 mg/l, no calibration is required.
Note:
Do not carry out a calibration if the concentration is lower than 0.10 mg/l.
3.
Press the key
and select the input function. If necessary, adjust the value for the
comparative measurement.
4.
Activate the calibration process by pressing the
key and in addition
.
Note:
The S200 recalculates the slope and the zero point deviation after each calibration.

The current slope/zero point deviation of the probe is displayed in the calibration menu.

Ex planation ‘Slope of probe’
The slope of the probe is a theoretical value, and is within a range of 5 mV and 100 mV. The
stored value is 35 mV. If the slope of the probe is outside the range, the probe should be
cleaned manually.
If necessary, the surface of the gold ring is to be cleaned.
6 . 6 . 1 . 3
Ex planation ‘Zero point of pr obe’
The zero point of the chlorine/chlorine dioxide/ozone probe is at 0 mV.
